3 Phase inveter options

Recommended Posts

Hi guys back again.

Ok so in the end it looks like it will be best to get a 3 phase inverter as our house is 3 phase and it seems it will be to much effort and cost to convert it over.

So I am looking into the 3 phase inverter options and would appreciate some input.

I am looking at options between 8kw - 12kw

As per my previous thread I would prefer a cheaper inverter and get extra battery and panels but I dont want to buy a complete piece of grabage.

So the obvious best and most expensive options are

  • Sunsynk Sun 8kW Three Phase LV Hybrid Inverter R43 929.00
  • Sunsynk Sun 10kW Three Phase LV Hybrid Inverter R50 204.00
  • Sunsynk 12kW 3 Phase Hybrid Inverter R60,950
  • Deye 12KW 3 Phase Hybrid Inverter  R53,800

Then the cheaper options are

  • Solis S5 8kW Dual MPPT 3-Phase Grid Tie Inverter  R20,884
  • Solis S5 10.0kW Dual MPPT 3-Phase Grid Tie Inverter R22,145
  • Solis S5 12.0kW Dual MPPT 3-Phase Grid Tie Inverter R24,483
  • Solis S5 15.0kW Dual MPPT 3-Phase Grid Tie Inverter R25,993

Cant seem to find local supplier for any other Deye 3 phase.
Did i miss any options?
Does anybody have experience with they Solis as they seem to be allot cheaper.

They also have 5 year standard warranty.

The price difference between 8kW and 15kW also seems very low.

I also cant seem to find Deye and Sunsynk 8kW or 10kW for 3 phase in local stores.

 

It this point I am thinking either Sunsynk Sun 8kW or Solis S5 12.0kW

Please let me know what you think

Be aware that the Solis inverters on this list are grid-tie inverters without inputs/outputs for a battery. Unlike the hybrid inverters, they need Eskom in order to run.

Your other option could be to investigate 3 Axpert/Mecer/Kodak inverters or similar operating in 3 phase mode, one inverter per phase.

Could you elaborate?
I got it here and it says three phase?

As far as know the only Sunsynk 3 phase machine available in SA is the 12kw and at some point soon the 50kw will be available

Do you know of any other 3 phase that I should consider?

Infini solar also has a 3 phase

Don't also disqualify the new Infinisolar by Voltronics. It's light years ahead of the older versions & has good lithium battery compatibility exactly the same as it's Single phase cousins like the OG7.2 & OG10.0. in Pylontech, FreedomWon & a few others to make a few. They come in 12kW & 15kW 3 phase flavours & can phase share by up to 150% & this was the unfortunate problem of the older version. The newer version which is branded as Blue mountain energy sold by Segen Solar is really a quality machine & is also IP65 rated & has 2 AC output ports that can be programmed & controlled remotely to stop discharge at a specified % SoC as derived from the Battery BMS. The Solar charge controller is High Voltage & rated up to 1000V. It's also NRS approved so it can be installed even in Cape town 🤣
